Pradip said: "A team of police took Nur and Nurul, captured the previous night, to Rajarchhara area in an operation to find other drug traders. However, upon reaching the site, the traders ambushed the police and started firing at them, prompting police to fire back."

Police brought Nur and Nurul to a hospital, where the on-duty doctors declared them dead. Four members of the police—Sub-Inspector Sanjib, Constable Al-Amin, Saiful Islam, Arsadul, and Sabbir— were also injured during the gunfight.

Korban was accused in several cases including of hijacking, illegal arms dealing, and the murder of a tourist, he said.

The OC said: "Acting on a tip-off, a patrol team of detective police went to the Khuruschool Bridge area, on an operation. However, upon seeing the police, a group of criminals started firing at the police, upon which the police were forced to fire back in self-defense."

Korban was rescued from the spot and admitted to a hospital, when the on-duty doctors declared him dead. Police recovered an LG gun and three rounds of cartridges from the spot.

All of the bodies have been sent to the Cox's Bazar Sadar Hospital morgue for autopsy.
